Actually...
Actually, care of an intact boy is easier than a circumcised one. No worry about re-adhesion or infection or pain relief every time urine gets in his wound until it heals. Then "only clean what is seen - just the outside - till it retracts in its own good time, usually not for years. More problems are caused by meddling and over-anxious parents than by having all one's genitals.
And since circumcision has its roots in sex-phobia (it was medicalised to prevent, "cure" and punish masturbation - J H Kellogg recommended circumcision for boys, carbolic acid for girls - but it was successful only in the last of those), you have no basis for thinking it is intact boys' parents who would leave them ignorant.
